I am sorry that I did not state my question clearly.

What I mean by data manipulation includes sort, merge, aggregate, transpose, data export and import, format, date & time handle, and so on, which might be not important to statistician.

I have use SAS and SPSS for a while and really want to use R as an alternative computing system. Unless R/S+ can provide strong functionality in data manipulation as SAS does, it is hard to compete with SAS in business rather than in academic.
